Phys.org / Chemists unlock Appel fluorination with potassium fluoride
Alcohols are among the most abundant building blocks in chemistry. Fluorinated compounds, meanwhile, are essential for many modern medicines, crop protection products and advanced materials. Converting one into the other, ...
Phys.org / New theory on how six‑tonne Stonehenge rock was transported from Scotland thousands of years ago: On a glacier
Built from stones weighing between 2 and 25 tonnes (2 to 28 tons), the structure of Stonehenge demonstrates a scale of construction hard to imagine before the invention of the wheel. The mystery deepens when you consider ...
Medical Xpress / Immune signals may help predict responses to therapies for difficult-to-treat depression
In a new study, researchers from The University of Texas MD Anderson Cancer Center have uncovered insights that may help explain how rapid-acting antidepressants, such as ketamine and psychedelics, can reduce symptoms of ...
Medical Xpress / Rat study finds early secondhand smoke exposure can alter tooth enamel mineralization
Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth. This was demonstrated in an animal model study conducted ...
Phys.org / Researchers investigate case of soft-tick borne relapsing fever in Austin area
Researchers at Baylor College of Medicine and the Texas Department of State Health Services have reported a likely case of soft tick-borne relapsing fever (STRF) in an Austin-area resident. Now, they highlight the growing ...
Phys.org / Scientists have found a new way molecules can cooperate at room temperature
What if glowing molecules could synchronize, much like fireflies flashing in unison? Researchers have discovered that molecules confined within tiny gold nanostructures can behave collectively, coordinating their interactions ...
Medical Xpress / Brain fluid structure may flag future dementia risk years before diagnosis
Dementia, a progressive loss of memory and decline in mental function that can be caused by various neurological conditions, is estimated to affect more than 57 million people worldwide. Identifying specific biological and ...
Medical Xpress / Cancer drug enables kidney transplant despite severe immune incompatibility
An international research team led by the Medical University of Vienna reports on a new treatment strategy that has made kidney transplantation possible for a patient with no realistic chance of receiving a suitable donor ...
Medical Xpress / AI blood assay detects liver cancer across diverse international populations
Researchers at the Johns Hopkins Kimmel Cancer Center validated an artificial intelligence (AI)-powered blood test that accurately detected liver cancer in people from two geographically and biologically distinct populations ...
Phys.org / Surface engineering advances mitochondrial transplantation as a potential therapeutic strategy
Inside almost every cell in our bodies are tiny structures called organelles that keep us alive and functioning. Among these are many bean-shaped mitochondria, often referred to as the cell's power plants because they generate ...
Tech Xplore / Hugging Face CEO calls for accountability after OpenAI hack
The chief executive of Hugging Face said Friday that developers should be held accountable if their AI models go rogue, after his startup faced a recent cyberattack by autonomous OpenAI software.
Phys.org / Early Cambrian fossil uncovers key buoyancy structure at the dawn of cephalopod evolution
Extant and ancient cephalopods—including octopuses, squids, extinct ammonites, cuttlefish and nautiluses—have all had to solve the problem of buoyancy, whether they have hard external shells or not.
